- The PCSS-8H is the versatile PC compatible serial interface card that
- supports eight separate RS-232 devices for input and output. The PCSS-8H is
- capable of addressing each UART separately and mapping each UART into the I/O
- address map of the standard DOC COM1: and COM2: communication channels. This
- unique feature provides the PCSS-8H with DOS compatibility on all eight ports.
- In fact, all of the ports are 100 percent compatible right down to the
- handshake lines. Furthermore, by using an on- board interrupt controller, only
- one interrupt line is used by the PCSS-8H, thereby allowing up to 32 ports per
- computer. The PCSS-8H is supplied with utility programs that permit easy
- command line port switching and an enhanced BIOS INT 14 device driver that
- allows simultaneous interrupt driven operation on all ports with automatic
- handshaking. Example programs, with source code, are furnished in Quick Basic+
- to demonstrate the PCSS-8H's ease of use with the INT 14 device driver. The
- individual addressability of each UART allows the PCSS-8H to be used with
- existing applications or operating systems such as Microport UNIX and SCO
- XENIX. The bracket assembly provided with the PCSS-8H, housing eight
- IBM-compatible DB25P connectors, attaches securely to the rear panel of a PC-AT
- or PC-XT. It does not interfere with the limited I/O area behind the computer's
- card slot and eliminates the unsightly cabling mess associated with many
- multiport cards on the market. Optional RS422 interfaces allow communications
- at distances of up to 4000 feet. An upgradable 4-port version, the PCSS-4H is
- also available.
